This register controls line loopback for tributaries #17 to #28 of SPE #1 and
tributaries #1 to #4 of SPE #2.
SPE1_LBEN[28:17]:
The SPE #1 loopback enable bits (SPE1_LBEN[28:17]) control line loopback
for tributaries #28 to #17 of SPE #1 of the SBI Interface. When
SPE1_LBEN[n] is set high, the data on tributary #n output by the SBI PISO
block is looped back to the tributary #n input of the SBI SIPO block. When
SPE1_LBEN[n] is set low, transmit data for tributary #n is provided by the
TCAS block (i.e. processed normally).
SPE2_LBEN[4:1]:
The SPE #2 loopback enable bits (SPE2_LBEN[4:1]) control line loopback for
tributaries #4 to #1 of SPE #2 of the SBI Interface. When SPE2_LBEN[n] is
